hydrochlorofluorocarbon, n. Chem.
Brit. |ˌhʌɪdrə(ʊ)ˌklɔːrəʊˈˌflʊərəʊˈˌkɑːb(ə)n|, |ˌhʌɪdrə(ʊ)ˌklɒrəˈˌflʊərəˈˌkɑːb(ə)n|, U.S. |ˈˌhaɪdroʊˌklɔroʊˈflɔroʊˌkɑrb(ə)n|, |ˈˌhaɪdroʊˌklɔroʊˈflʊroʊˌkɑrb(ə)n|[see also chloro- comb. form1, fluoro- comb. form.]
[‹ hydro- comb. form + chloro- comb. form2 + fluorocarbon n. Compare earlier hydrofluorocarbon n.]
Any of a class of partly chlorinated and fluorinated hydrocarbons, some of which are used as an alternative to CFCs in foam production, refrigeration, etc. Abbreviated HCFC.
1977Abstr. Papers 173rd Meeting Amer. Chem. Soc. (Physical Chem.) 9 Should replacement of CFCl3 and CF2Cl2 become necessary, it is likely that hydrochlorofluorocarbons..will be used. 1989Chicago Tribune (Nexis) 14 July 1 [The] substitute is a compound of two hydrochlorofluorocarbons—HCFC-123 and HCFC-141B. Each has a much shorter life than CFC-11. 1990New Scientist 30 June 33/3 As for CFC substitutes, the hydrochlorofluorocarbons (HCFCs).., the most likely outcome is that they will be included in the protocol for the first time under a special resolution covering so-called ‘transitional ozone-depleting substances’. 1999Chem. in Brit. Mar. 42/1 A typical sticky foam formulation is..20 per cent chlorinated hydrocarbon as a fire retardant..and 30 per cent hydrochlorofluorocarbon (HCFC) or chlorofluorocarbon (CFC) as the solvent and blowing agent. |
